Title: Improvements in or relating to receivers for modulated high frequency waves
IPC: H03D1/16
Filed: 1932-06-06
Abstract: 393,415. Valve detecting circuits. TELEFUNKEN GES. FR DRAHTLOSE TELEGRAPHIE, 12, Hallesches Ufer, Berlin. June 6, 1932, No. 15956. Convention date, June 6, 1931. [Class 40 (v).] In order to provide automatic gain control in a wireless receiver, the rectifier stage is continuously in operation (i.e. not quenched) and the relation between the input voltage and output current is logarithmic so that the lowfrequency output is proportional to the degree of modulation of the input high-frequency wave and independent of its mean amplitude. The rectifier stage may include a photoelectric cell activated by a light source modulated by the signal input, as the current output from such a cell is approximately a logarithmic function of the light strength ; alternatively a gas discharge tube may be utilized as the rectifier by virtue of its saturation phenomena. The Figure shows a rectifier stage employing ordinary thermionic valves, which normally exhibit the required logarithmic characteristic over a small part of the upper bend of their characteristic curves. The useful range is extended by employing several valves 1, 2, 3 in parallel and biased to different points on their characteristics by batteries 9, 10, 11 and chokes 6, 7, 8.

Inventor: MICHAELS ALAN SHERMAN
IPC: C08J5/00
Filed: 1966-04-13
Abstract: A method of shaping a solid non-plastic water-insoluble ionically cross-linked polyelectrolyte formed by the interaction of two water-soluble synthetic linear organic polymers, one of which contains dissociable anionic groups and the other cationic groups, by imbibing into the polyelectrolyte from aq. solution calcium nitrate, bromide or chloride and/or sodium bromide, evaporating at least a portion of the water to leave a solid plastic composition which is then subjected to pressure and heat to shape it e.g. into a sheet. The polyelectrolyte may be formed from sodium polystyrene sulphonate and polyvinyl benzyltrimethyl ammonium chloride.  The solid plastic composition may contain 10-150% of the salt which may be leached from the shaped composition.ALSO:A paper sheet is impregnated with a polyelectrolyte by placing on the surface of a sheet of filter paper the polyelectrolyte and press-moulding them between layers of polyester film to produce the paper sheet impregnated with the polyelectrolyte.  The polyelectrolyte was made by adding sodium polystyrene sulphonate with an aq. solution of polyvinyl benzyltrimethyl ammonium chloride to a solution of calcium nitrate, 1, 4-dioxane and water and drying the resultant precipitate.  The impregnated paper sheet was washed with water to leach out the calcium nitrate in the polyelectrolyte.

Lasting and pulling- over. - In a machine of the type described in Specification 12304/03, the forepart of the upper is disposed on the shoe bottom by mechanism acting on the upper on the shoe bottom at substantiallv different distances from the margin of the shoe bottom at different parts around the forepart. The invention is described as applied to the making of felt shoes with wide toes. A felt upper, previously side-lasted and with the edges of the upper sewn together up to the rear of the toe portion, as shown in Fig. 9, is positioned in the machine. A single gripper 16, Fig. 2, at the toe then stretches the upper over the last. A pair of wiper plates 60, Fig. 9, then wipe the toe of the upper over the last. A second pair of wiper plates 80 are then actuated by adiustable cam-surfaces 92 mounted on the usual inwardly swinging arms 90, Fig. 2. The rear edges of these plates reach a position substantially farther inwards from the margin of the last than that of the plates 60, and their pivots 84 are so situated that the inward movement has a slight forward component. Recesses in the advancing edges of the wiper plates determine the location of the folds shown in the upper. The tack-holders are arranged in alignment with these recesses, moving with the wiper-plates, so that the various tacks are inserted at correct positions in the folds and also at different distances from the margin of the last. The side tackers are mounted to swing about axes 120, 122, Fig. 2, inclined to the plane of the shoe bottom to give clearance for the margin of the upper before the wipers advance over the shoe bottom. The work support has a threepoint bearing on the shoe bottom, two spaced studs 4, Fig. 9, engaging the fore-part, and a member projecting from the heel rest engaging the bottom of the heel.

Title: Improvements in or relating to refrigeration systems
IPC: F25B1/00
Filed: 1964-04-20
Abstract: 996,852. Refrigerating. STAL REFRIGERATION A.B. April 20, 1964 [May 30, 1963], No. 16288/64. Heading F4H. A refrigerating system comprises an evaporator located at a level substantially below that of the compressor and condenser, a liquid. vapour separator, a down-pipe for conveying refrigerant from either the liquid-vapour separator or an expansion valve to the evaporator, a spring-loaded valve at the bottom of the downpipe for controlling the refrigerant supply to the evaporator and a riser pipe surrounding the down-pipe for returning refrigerant from the evaporator to the separator. As shown, refrigerant from a compressor 1 passes via a condenser 2, heat exchanger 7 and expansion valve 3 to a down-pipe 13 which is connected at its upper end to a liquid-vapour separator 6 and at its lower end to evaporators 4, 5. The latter are disposed in the hold of a ship and the compressor, condenser and separator are located on the ship's deck. A riser pipe 19 surrounding pipe 13 returns refrigerant from evaporators 4, 5 to separator 6. Expansion valve 3 is intermittently operated by a controller 11 which periodically opens a valve 12 in a line 10 connecting a level sensing device 9 for the condenser to the valve 3 so that the latter is controlled in response to the liquid level in the condenser when valve 12 is open. When valve 3 opens, refrigerant liquid in pipe 13 is forced into the evaporators through a spring-loaded valve 16 which ensures that the pressure in the evaporators is substantially independent of the liquid head in pipe 13 and that equal amounts of refrigerant are supplied to the evaporators. When valve 3 is closed and the pressure in pipe 13 falls, a pressure-responsive valve 15 opens to admit liquid refrigerant from the separator 6 to pipe 13. When the evaporators 4, 5 are to be defrosted or used as heaters the cooling water supply to condenser 2 is terminated and a valve 21 is opened to by-pass valve 3 and supply hot gaseous refrigerant to the evaporators. Liquid refrigerant from the riser 19 is discharged into a funnel 25 in separator 6 and then passes through a pipe 28 via heat exchanger 7, the refrigerant being reintroduced into the separator at a point immediately above the inlet of the suction line 20. Excess liquid refrigerant overflows from funnel 25 to collect in the bottom of the separator for return to the down-pipe via valve 15.

Filed: 1962-04-30
Abstract: 969,804. Closed liquid coolant circulation systems. G. BAYARD. April 30, 1962 [May 13, 1961], No. 16412/62. Heading F4U. Apparatus for cooling the liquid coolant, e.g. of electronic equipment in an aircraft, comprises an air cooled heat exchanger 11, means 7 capable of causing the liquid to bypass the heat exchanger when the temperature of the cooling air rises above a predetermined value, means leading from the heat exchanger and from the by-pass to convey the liquid to a pair of evaporators 16, 17 arranged in series, the evaporators containing a second liquid, e.g. methyl alcohol, and means capable of controlling the boiling temperature of said second liquid. As shown, liquid to be cooled enters distribution cock 7 which is controlled by a heat sensitive probe 9 which records the temperature of the air-cooling heat exchanger 11. If the temperature sensed is below e.g. 50‹ C. then cock 7 diverts the liquid through the heat exchanger 11, if above, then the heat exchanger is by-passed. Both by-pass and heat exchanger liquid enters evaporators 16 and 17 before finally flowing back to the equipment to be cooled via pipe 5. The required amount of cooling of the liquid in the evaporators is obtained when the methyl alcohol is subjected to a pressure of 700 gm. per sq. cm. equivalent to an altitude of 3000 metres. When the aircraft rises above this altitude regulator 32 acts as an exhaust valve for both evaporators and restores the pressure in the evaporators to 700 gm. per sq. cm. via stacks 26 and 27 and valve 31. When the aircraft descends below 3000 metres the regulator 32 is set directly in communication with the atmosphere and the methyl alcohol in evaporator 16 boils off at a higher temperature and does not sufficiently cool the liquid. The evaporator 17 however is subjected to a depression through regulator 33 which communicates with extractor 35 which restores inside evaporator 17 a pressure of 700 gm. per sq. cm. Valve 31 remains closed while extractor 35 is in operation.
